Uthotho: Kutheni ii-Drill Bits zingaphumeleli | Inqaku le-14
Amagama angundoqo: ukuqengqeleka kwe-drill bit, i-TIR, ukujikeleza kwemingxuma, umngxuma omkhulu, ukugqobhoza ngokuthe tye, ukuqengqeleka kwe-radial, ukuphambuka kwe-long drill bit, ukuhlolwa kwe-HSS drill bit, ukuqengqeleka kwe-chuck vs. ukugxobhoza, ukuchaneka kwemingxuma

Inqaku lokugqibela kolu ngcelele lijonge ukuba yintoni elawula ukugaywa kwe-full ground bit — i-outer diameter, i-back taper, i-web taper, kunye ne-flute-to-flute symmetry. Umgca omnye kwelo nqaku ukhombe phambili kule: indlela i-outer diameter kunye ne-margin ezisemgangathweni ngayo zibonakala ngqo kwi-radial runout ye-bit xa sele igxothiwe. Eli nqaku lichaza oko. I-Runout yindawo apho ukugaywa ngokuchanekileyo kubamba khona ukugaywa okanye kungagcini — kwaye yeyona nto inkulu eyahlula umngxuma ongqukuva komkhulu, ongaphandle kwesangqa.

Ukuqalisa, Ngokweentsingiselo Ezicacileyo

Susa isigama uze uqalise ukujikajika uphendule umbuzo omnye: ingaba i-drill ithe tye? I-drill bit enomgca wayo ophakathi wejometri ihambelana ne-axis yayo yokujikeleza iya kutshaya i-radius efanayo kuyo yonke indawo njengoko ijikeleza. I-bit egobile kancinci, okanye ewileyo embindini wayo, ayigungqi - iyagungqa, ngendlela ivili elingalinganiyo eliyenza ngayo. Oko kujikajika, okulinganiswe nge-dial indicator, yinto imboni eyibiza ngokuba yi-TIR: i-total indicated runout.

Kufanelekile ukwahlula oku ngokucacileyo ekuhambeni, esikugubungele kwiNqaku lesi-8. Ukuhamba kwenzeka kwangoko xa umbhobho uchukumisa umphezulu okokuqala - yingxaki ye-chisel-edge kunye ne-lip-symmetry, kwaye iyayeka kwangoko imida ingena eludongeni lomngxuma. Ukuhamba komgca kwahlukile: xa iqhekeza liqhuma kwaye lijikeleza, likho kulo lonke ukusika, ukusuka ekudibaneni kokuqala ukuya kubunzulu bokugqibela. Ukuhamba yingxaki yokuqala. Ukuhamba komgca yingxaki yokusika ngokupheleleyo, yiyo loo nto iziphumo zayo zibonakala ngokwahlukileyo - kungekhona kwindawo yomngxuma, kodwa ngobukhulu bomngxuma, ukujikeleza, kunye nemeko yodonga.

Ukuqalisa kweendawo ezimbini kuvela

Xa umthengi ebona ingxaki yokuphelelwa yimali, unobangela phantse usoloko ungomnye wemibini, kwaye ukwahlukanisa izinto kubalulekile kuba ukulungiswa kwahlukile ngokupheleleyo.

•Icala lebhithi (ukwenziwa):Ukuba iqhekeza ngokwalo alithanga ngqo — ukusuka kuxinzelelo olushiyekileyo olukhutshwe emva konyango lobushushu, okanye ekubeni ligayiwe ngaphandle kokubanjwa embindini walo wokwenyani — ububanzi bangaphandle buyinto engaqhelekanga ekuqaleni. Akukho bungakanani bokugxobhoza ngononophelo obulungisa iqhekeza elalisele lingekho embindini xa lishiya ivili lokusila. Le yingxaki yokwenziwa, kwaye ilawulwa kwinqanaba lokusila nokuhlolwa.

•Icala lokuseta (usetyenziso):I-chuck okanye i-collet egugileyo, iitships okanye ioyile ebambeke emihlathini, ukunamathela kakhulu, okanye ukuqengqeleka kwi-spindle ngokwayo konke kuya kubangela ukugungqa nokuba kukwi-bit ethe tye ngokugqibeleleyo. Le yimeko yokusetyenziswa, ayilophelo kwi-drill.

Kutheni iiLong Drill Bits zifuna ingqwalasela esondeleyo?

Ubude bukhulisa nayiphi na impazamo yokuthe tye esele ikho. Ukuphambuka okuncinci kwe-angular okulinganiselweyo kancinci kwi-short bit kuvelisa ukujija okukhulu kakhulu kwincam ye-long bit - isizathu esifanayo sokuba intonga ende ijijeke ngakumbi esiphelweni sayo kune-short bit ukuze kube nomlinganiselo ofanayo wokugoba. Kukwakho nesizathu sokuba ii-long drill kunzima ukuzibamba ngokuthe ngqo xa zisilwa kwasekuqaleni: ngaphandle kwenkxaso eyaneleyo ngexesha lenkqubo, zinotyekelo lokufumana isaphetha esincinci esingayi kuboniswa yi-standard-length bit. Abathengi abasebenza ngee-extra-long drills okanye ze-aircraft-long drills banelungelo lokubuza umthengisi ngokuthe ngqo ukuba ulawulo lwe-runout lubonakala njani kuloo mgama wobude, endaweni yokucinga ukuba luhambelana ne-standard-length spec.

Yintoni Ebangela Ukuba Umthengi Alahlekelwe Yimali?

Ngenxa yokuba ukuqukuqela kombane kukho kuyo yonke i-cut, iziphumo zayo zihambelana nenkqubo kunokuba zahlulwe zibe yinxalenye enye:

•Imingxunya emikhulu kakhulu.Ububanzi obusebenzayo bombhobho wokugrumba bukhulu kunobukhulu bawo obuqhelekileyo, kwaye umsantsa uyanda njengoko ukuqengqeleka kwamanzi kusanda.
•Imingxunya engaphandle kwesangqa.I-drill engasebenzi kakuhle ayinakunqumla umngxuma ongqukuva — oku akuyonto inokwenzeka, yimiphumo ethe ngqo yesixhobo esingekho embindini. Impazamo ye-Roundness ilandelela i-runout phantse enye emva kwenye.
•Ukwaphuka kwe-margin okungalinganiyo.Icala lomda ophethe umthwalo omninzi liguga ngokukhawuleza kunelinye, kwaye ngenxa yokuba ukuguga akulingani, kulula ukuphoswa kukujonga okubonakalayo ngokukhawuleza.
•Iindonga ezirhabaxa zemingxuma.Iimpawu zokujika ezirhoxayo kunye nokugqitywa okurhabaxa ziimpawu eziqhelekileyo, ingakumbi xa umbane unyuka.
•Ubomi besixhobo obufutshane.Ubomi bezixhobo buyehla ngokungalinganiyo njengoko ukutyibilika kusanda — ukuncitshiswa okuncinci kokutyibilika kuvelisa ukwanda okukhulu kwinani lemingxuma enokunqunyulwa yidrill ngaphambi kokuba ifune ukugaywa ngokutsha okanye ukutshintshwa.

Ezi ziphumo zidibana ngqo nenqaku lokugqibela. Ukunyamezelana okuncinci ukuya kwi-h8 ephepheni kusenokungaluboni olo phawu lokunyamezelana emngxunyeni ogqityiweyo ukuba ukuqhutywa kombane akulawuleki — nto leyo ebaluleke ngokuthe ngqo kwiimvume zokulungisa, ukuphazamiseka, kunye nayo nayiphi na imisebenzi esezantsi eyakhelwe kubungakanani obuhambelanayo bomngxunya.

Indlela Abathengi Abanokwazi Ngayo Ukuba Ingxaki Iphi

Isalathisi sokudayela esichasene ne-chucked bit sinika i-TIR ngokuthe ngqo — iidrill ezincinci zinobuthathaka ngakumbi kumlinganiselo othile wokubaleka kunezinkulu, ngoko ke uluhlu olwamkelekileyo luyaqina njengoko ububanzi buhla.

Ngaphaya komlinganiselo, uvavanyo olulula lokutshintshana ludla ngokwahlula unobangela:
•Tshintshana kwi-drill eyahlukileyo kwaye ingxaki iyanyamalala:Ingxaki ixhomekeke kuloo nto — nokuba iqondile okanye indlela eyayigayiwe ngayo.
•Tshintsha oomatshini okanye utshintshe i-chuck kwaye ingxaki iyanyamalala:Ingxaki ixhomekeke kwisetingi — imeko ye-chuck, i-spindle runout, okanye i-stickout — kungekhona i-drill.
•Akukho nanye i-swap eyisombululayo:Kufanelekile ukujonga ubude bokunamathela, iiparameter zokuphakelwa, kunye nokuqina kokusebenza ngaphambi kokuba ucinge ukuba i-bit okanye umatshini yiwo onempazamo.

Oku kubonisa indlela yokuxilonga ekwiNqaku lesi-8: ukwazi apho unobangela ukhoyo kuqinisekisa ukuba inyathelo elilandelayo elifanelekileyo yingxoxo nomthengisi okanye ukulungiswa kwindawo yevenkile.

Oku kuthetha ukuthini xa uthelekisa ababoneleli

Ukunyamezelana kokugaywa kunye nolawulo lokubaleka kwe-runout zizinto ezimbini ezahlukeneyo, kwaye kufanelekile ukuzibuza ngazo zombini ngokwahlukeneyo. Ngaphambi kokuthelekisa iikowuteshini:
•Ingaba ukuvuza kwamanzi kuyajongwa emva kokusila, kwaye kusekelwe phi - isiqwenga sokuqala kuphela, okanye ukusampulwa okuqhubekayo ngebhetshi?
•Ngaba kukho umgangatho owahlukileyo wokuqhuba ii-drill ezinde okanye ezinde kakhulu, xa ucinga ukuba ubude bungakanani obuyandisa impazamo yokuthe tye?
•Ngaba umthengisi angabelana ngoko kufunyanwa luhlolo lwakhe — kungekuphela nje ukunyamezelana okufunwayo kwiphepha leenkcukacha, kodwa kuphi apho kuqinisekiswe khona?

Kwimiqolo yethu, iibhithi zomhlaba zidlula kuvavanyo lokuqala oluqinisekisa ububanzi bangaphandle kunye nokubaleka ekuqaleni kwebhetshi nganye, kulandele uhlolo lweendawo ezisetyenziswayo ngexesha lokuqalisa — uhlobo olufanayo oluchazwe kwinqaku lokugqibela, olusetyenziswe ngokukodwa kuluhlu oluthe tye kunye nokubaleka kwe-radial endaweni yobubanzi bodwa.

Kutheni i-Drill Bits Ingaphumeleli luluhlu lobuchwephesha olubhalwe liqela lethu lemveliso. Inqaku ngalinye ligxile kwinto enye ethile ekusebenzeni kwe-drill bit - ukusuka kwizinto eziluhlaza ukuya ekupakisheni. Injongo ilula: ukunceda abathengi baqonde ukuba bathenga ntoni, kunye nemibuzo abanokuyibuza.
